Acquia: The Open Source Value Proposition

Planet Drupal - Mon, 14/07/2014 - 16:36

Every so often, advocates and vendors of proprietary/closed source software attempt a FUD (Fear, Uncertainty & Doubt) campaign of comment and link-baiting in order to reframe the conversation around Open Source. The arguments brought up in these discussions are predictable and generally straw man arguments that hold little water, so I wanted to take time to break these down and show the real value proposition of Open Source platforms, web content management systems generally, and Drupal specifically.

legomenon.io: Function scope & Drupal cache

Planet Drupal - Mon, 14/07/2014 - 13:48
Function scope & Drupal cache

When developing with caching in mind it's important to consider functionality scope. For example, writing code which is per visitor specific in PHP with caching support ahhh =O. While rewriting that same functionality in JavaScript offers us a quick and cache friendly solution. Consider the following examples.

/** * Implements hook_preprocess_TEMPLATE(). */ function THEME_preprocess_page(&$variables) { $detect = mobile_switch_mobile_detect(); if ($detect['ismobiledevice'] && !$detect['istablet']) { $variables['logo'] = url('sites/all/themes/THEME/images/logo_rev.png', array('absolute' => TRUE)); } } /** * Custom header block content. */ function _header_search_content_block() { $detect = mobile_switch_mobile_detect(); $form = drupal_get_form('search_form'); // Format search form. $form['basic']['keys']['#attributes']['placeholder'] = t('Search'); $form['basic']['keys']['#title_display'] = 'invisible'; $form['basic']['keys']['#size'] = 20; if ($detect['ismobiledevice'] || $detect['istablet']) { $form['basic']['keys']['#size'] = 15; } $items = array( render($form), l(t('another item'), 'link') ); return theme('item_list', array('items' => $items)); }

Clearly this code can be easily rewritten in JavaScript. However with caching enabled we'll need a method to pass our device detection variables. The only function which is exempt from Drupal cache is boot(). Calling drupal_add_js() directly from hook_boot() fails; the following example is using Mobile Switch and illustrates a work around.

/** * This is an example of how to manipulate site elements with page * caching enabled. We pass our detection variables to js settings * which we can then act on. */ function MODULE_boot() { $detect = mobile_switch_mobile_detect(); // Whatami. $_SESSION['detect'] = array( 'ismobile' => $detect['ismobiledevice'], 'istablet' => $detect['istablet'] ); } /** * Implements hook_init(). */ function MODULE_init() { drupal_add_js(array('detect' => $_SESSION['detect']), 'setting'); } /** * @file * MODULE.theme.js */ (function($) { Drupal.behaviors.MODULE = { attach: function(context, settings) { // Swap logo for mobile. if (settings.detect.ismobile && !settings.detect.istablet) { $('.site-branding__logo img').attr('src', Drupal.settings.basePath + 'sites/all/themes/THEME/images/logo_rev.png'); } // Search box size. if (settings.detect.ismobile || settings.detect.istablet) { $('.l-region--header .search-form input.form-text').attr('size', 15); } } }; }(jQuery));

These flags can of course be used for more fruitful purposes =)... Note, this sort of consideration is most likely second nature to most Xd.

CTI Digital: Installing Drush using Composer on Mac OS X 10.9 Mavericks

Planet Drupal - Mon, 14/07/2014 - 12:46
Following on from our previous guide “Creating and using an public/private SSH key-pair in Mac OS X 10.9 Mavericks” in which we walked you through the process of setting up Git on Max OS X 10.9 Mavericks, we’re now going to look at installing Drush using Composer. If you’re never heard of Drush before, the description provided on the  Drush GitHub repository offers a succinct and accurate explanation of what Drush is and the tools it makes available to you: Drush is a command line shell and Unix scripting interface for Drupal. If you are unfamiliar with shell scripting, reviewing the documentation for your shell (e.g. man bash) or reading an online tutorial (e.g. search for "bash tutorial") will help you get the most out of Drush. Drush core ships with lots of useful commands for interacting with code like modules/themes/profiles. Similarly, it runs update.php, executes sql queries and DB migrations, and misc utilities like run cron or clear cache. Ultimately our goal in these series of guides is to give anyone both experienced and inexperienced alike the knowledge and skills required to configure their system so that an installation of Drupal can be run from it with a suite of tools available for them to use from the get-go. Let’s begin. Installing Composer Rather than installing Drush manually, we’re going to let a tool called Composer do all the hard work for us. Composer is a tool for handing dependency management the full description for which can be found on the Composer site. In a nutshell though, the following sums up Composer well: Composer is a tool for dependency management in PHP. It allows you to declare the dependent libraries your project needs and it will install them in your project for you. Let’s install Composer. Open a new instance of the Terminal by either navigating to the Applications folder within the finder followed by the Utilities sub-folder, or alternatively by pressing “Cmd+Space” and typing “Terminal” followed by the “Enter” key. Once open, type the following command to ensure you’re in your home directory: cd ~/ To download composer, type the following command into the Terminal and hit enter: curl -sS https://getcomposer.org/installer| php At this point you could type “~/composer.phar --help” into the command line and you’ll most likely get a list Composer help documentation, but we want to be able to access Composer simply by typing the command “composer”, so let’s move the *.phar file into our “/user/local/bin” directory. Note: On a fresh installation of OS X 10.9, the “/usr” directory will very likely be empty. If this is the case, to enable us to successfully move Composer to “/usr/local/bin/composer” you’ll need to type the following two commands “sudo mkdir /usr/local” and “sudo mkdir /user/local/bin”. After typing the first command, you may be prompted for your system password. Simply enter it to continue. Now we’re all set to move Composer. To do this, type the following command into the Terminal: mv composer.phar /usr/local/bin/composer Note: If you get an error trying to move the file, prefix the command above with “sudo” and try again. We should now be able to type “composer” into the terminal and get something other than an error returned. Try this out by typing “composer” and hitting enter. Adding the Composer “bin” directory to our path Once Drush is installed, we will be able to type “~/.composer/vendor/bin/drush” followed by the Drush command of our choice, but who wants to do that every time?  To be enable the ability to type “drush” followed by our command we need to add Composer’s bin directory to our path. In your home directory “~/“ type the command “nano ~/.bash_profile” and add the following line to the file that opens up: export PATH="$HOME/.composer/vendor/bin:$PATH" Quit Nano, by pressing “Ctrl+X” and when asked if you wish to save the document type “Y” and hit “Enter”. Finally we need to re-source our “.bash_profile” file by typing “source ~/.bash_profile” into the Terminal (alternatively you can quit and re-open the Terminal). Installing Drush At this point, installing Drush is a piece of cake. Simply type the following into the Terminal and hit “Enter” composer global require drush/drush:dev-master Drush should now be installed. To ensure it is, type “drush” into the command line and you should see a series of Drush help documentation. If you had any problems following this guide feel free to get in touch with me on Twitter at @craigperks

Wunderkraut blog: Configuration Entities in Drupal 8

Planet Drupal - Mon, 14/07/2014 - 11:10

With the overhaul of many API's in Drupal 8, one of the new kids on the block is the configuration system with its integration with the entity API. This means that we can now define configuration entities (that work much like the regular content entities) for the purpose of managing more complex configuration. For example, a View is a configuration entity and so is a field or an image style.

In this article we will look at how to define a configuration entity type that will serve a simple purpose, describe dummy flower configuration entities. We will do so in a module called flower and will use the alpha13 release of Drupal 8 to do it.

Before we get started, let's define a practical goal for this tutorial. As I said, we will have a flower config entity type with a couple of properties: name, number of petals, color and season. And by the end, we will have a fully fledged UI to create and manage them. The final code you can also find in this repository.

So let's begin.

The configuration entity interface

The first thing we need to do is define an interface our Flower entity type class can implement and that extends the default ConfigEntityInterface. So inside of our module's src/ folder, create a file called FlowerInterface.php with the following interface:

/** * @file * Contains \Drupal\flower\FlowerInterface. */   namespace Drupal\flower;   use Drupal\Core\Config\Entity\ConfigEntityInterface;   /** * Provides an interface defining a flower entity type. */ interface FlowerInterface extends ConfigEntityInterface {   }

As you can see, we are just extending the default configuration entity interface without adding any methods to it (which is possible).

The configuration entity class

Next, we will focus on the crux of defining our own configuration entity class. Go ahead and create a folder inside the src/ directory called Entity, and within it, a file called FlowerEntity.php:

/** * @file * Contains \Drupal\flower\Entity\FlowerEntity. */   namespace Drupal\flower\Entity;   use Drupal\Core\Config\Entity\ConfigEntityBase; use Drupal\Core\Config\Entity\ConfigEntityInterface; use Drupal\flower\FlowerInterface;   /** * Defines a Flower configuration entity class. * * @ConfigEntityType( * id = "flower", * label = @Translation("Flower"), * fieldable = FALSE, * controllers = { * "list_builder" = "Drupal\flower\FlowerListBuilder", * "form" = { * "add" = "Drupal\flower\Form\FlowerForm", * "edit" = "Drupal\flower\Form\FlowerForm", * "delete" = "Drupal\flower\Form\FlowerDeleteForm" * } * }, * config_prefix = "flower", * admin_permission = "administer site configuration", * entity_keys = { * "id" = "id", * "label" = "name" * }, * links = { * "edit-form" = "flower.edit", * "delete-form" = "flower.delete" * } * ) */ class FlowerEntity extends ConfigEntityBase implements FlowerInterface {   /** * The ID of the flower. * * @var string */ public $id;   /** * The flower name. * * @var string */ public $name;   /** * The flower color. * * @var string */ public $color;   /** * The number of petals. * * @var int */ public $petals;   /** * The season in which this flower can be found. * * @var string */ public $season;   }

What we have here is a simple class defining the entity properties we want (name, id, color, number of petals and season). This class extends the default ConfigEntityBase class and implements our interface. What happens above the class definition is what's interesting though.

Using annotations, we are basically telling Drupal about our Flower entity type.

The @ConfigEntityType tells Drupal that this is a configuration entity type (as opposed to a plugin or something else). Within its definition, we have an array-like structure with the following information (I will only mention the keys that are not super obvious):

  • label - the label of the entity type passed through the translation system.
  • fieldable - the configuration entities are not fieldable, but the content entities are. Since we are using the same entity API, we can specify this.
  • controllers - all the classes needed to manage these entities. The list_builder class will provide an admin overview interface of the entities, whereas the form classes are used to perform the CRUD operations through the UI.
  • config_prefix - a configuration identifier
  • entity keys - mapping of the main entity keys to the entity properties we defined. For instance, when we call the label() method on the entity object, it will return the flower name.
  • links - administration links for editing and deleting entities with values referencing routes. Specifying them here will make Drupal add them automatically to the operations column on the entity overview page (we'll see this in a minute).

For more information about the structure of an entity class annotation, follow this documentation page.

The entity forms

The next thing we need to do is create the forms we referenced in the annotations above: for adding, editing and deleting flower entities. The cool thing is that the form for adding can be reused for editing as well. For delete, we extend a special class that gives us all we need for a confirmation form. But first, the add/edit form (FlowerForm.php) inside of the src/Form/ folder:

/** * @file * Contains \Drupal\flower\Form\FlowerForm. */   namespace Drupal\flower\Form;   use Drupal\Core\Entity\EntityForm; use Drupal\Core\Entity\EntityInterface; use Drupal\Core\Entity\EntityTypeInterface; use Drupal\Core\Url;   /** * Class FlowerForm * * Form class for adding/editing flower config entities. */ class FlowerForm extends EntityForm {   /** * {@inheritdoc} */ public function form(array $form, array &$form_state) {   $form = parent::form($form, $form_state);   $flower = $this->entity;   // Change page title for the edit operation if ($this->operation == 'edit') { $form['#title'] = $this->t('Edit flower: @name', array('@name' => $flower->name)); }   // The flower name. $form['name'] = array( '#type' => 'textfield', '#title' => $this->t('Name'), '#maxlength' => 255, '#default_value' => $flower->name, '#description' => $this->t("Flower name."), '#required' => TRUE, );   // The unique machine name of the flower. $form['id'] = array( '#type' => 'machine_name', '#maxlength' => EntityTypeInterface::BUNDLE_MAX_LENGTH, '#default_value' => $flower->id, '#disabled' => !$flower->isNew(), '#machine_name' => array( 'source' => array('name'), 'exists' => 'flower_load' ), );   // The flower color. $form['color'] = array( '#type' => 'textfield', '#title' => $this->t('Color'), '#maxlength' => 255, '#default_value' => $flower->color, '#description' => $this->t("Flower color."), '#required' => TRUE, );   // The number of petals. $form['petals'] = array( '#type' => 'textfield', '#title' => $this->t('Petals'), '#maxlength' => 255, '#default_value' => $flower->petals, '#description' => $this->t("The number of petals."), '#required' => TRUE, );   // The season. $form['season'] = array( '#type' => 'select', '#options' => array( 'Spring' => 'Spring', 'Summer' => 'Summer', 'Automn' => 'Automn', 'Witer' => 'Winter' ), '#title' => $this->t('Season'), '#maxlength' => 255, '#default_value' => $flower->season, '#description' => $this->t("The season in which this flower grows."), '#required' => TRUE, );   return $form; }   /** * {@inheritdoc} */ public function save(array $form, array &$form_state) {   $flower = $this->entity;   $status = $flower->save();   if ($status) { // Setting the success message. drupal_set_message($this->t('Saved the flower: @name.', array( '@name' => $flower->name, ))); } else { drupal_set_message($this->t('The @name flower was not saved.', array( '@name' => $flower->name, ))); } $url = new Url('flower.list'); $form_state['redirect'] = $url->toString();   }   }

In our FlowerForm class we are extending the Drupal EntityForm class and implementing 2 of its methods: form() and save(). In the first one, we define a regular Form API form very similar to what we do in Drupal 7. But there are a few cool new things happening there as well:

  • We extend the parent form and add our elements to that definition.
  • We get the configuration entity object from the entity property of the parent class.
  • We check the operation being performed on the entity and if the user is editing it, we change the title of the page to reflect this
  • Instead of using the procedural t() function, we access $this->t() on the parent class for best practice.
  • We access the config entity public properties and set them as the defaults in the form elements' definition.
  • For the machine_name, we use the flower_load() helper function (that we will need to define in our .module file) in order to automatically check whether an entity with that ID already exists.

In the save() method we perform the simple operation of saving the entity object to the configuration system. Couldn't get simpler than this. And after the save is performed, we redirect to the flower entity overview page. Here we use the Url class to build a url object based on a route (that we will define later).

Next, let's quickly create the delete form.

Inside the same src/Form/ folder, create a FlowerDeleteForm.php file with the following class:

/** * @file * Contains \Drupal\flower\Form\FlowerDeleteForm. */ namespace Drupal\flower\Form;   use Drupal\Core\Entity\EntityConfirmFormBase; use Drupal\Core\Url;   /** * Form that handles the removal of flower entities. */ class FlowerDeleteForm extends EntityConfirmFormBase {   /** * {@inheritdoc} */ public function getQuestion() { return $this->t('Are you sure you want to delete this flower: @name?', array('@name' => $this->entity->name)); } /** * {@inheritdoc} */ public function getCancelRoute() { return new Url('flower.list'); } /** * {@inheritdoc} */ public function getConfirmText() { return $this->t('Delete'); } /** * {@inheritdoc} */ public function submit(array $form, array &$form_state) {   // Delete and set message $this->entity->delete(); drupal_set_message($this->t('The flower @label has been deleted.', array('@label' => $this->entity->name))); $form_state['redirect_route'] = $this->getCancelRoute();   } }

With this form class we are extending the Drupal EntityConfirmFormBase that provides us with all we need for a delete confirmation form. By implementing these self-explanatory methods, we take care of the entity delete process. Finally, it's time to define the admin overview page.

The entity list builder

As we declared when defining the config entity class, we now need a class file responsible for building the overview page of our entities. So straight in the src/ folder of our module you can create a FlowerListBuilder.php class file with the following class:

/** * @file * * Contains Drupal\flower\FlowerListBuilder */   namespace Drupal\flower;   use Drupal\Core\Config\Entity\ConfigEntityListBuilder; use Drupal\Core\Entity\EntityInterface;     class FlowerListBuilder extends ConfigEntityListBuilder {   /** * {@inheritdoc} */ public function buildHeader() { $header['label'] = $this->t('Name'); $header['color'] = $this->t('Color'); $header['petals'] = $this->t('Number of petals'); $header['season'] = $this->t('Season'); return $header + parent::buildHeader(); }   /** * {@inheritdoc} */ public function buildRow(EntityInterface $entity) {   // Label $row['label'] = $this->getLabel($entity);   // Color $row['color'] = $entity->color;   // Petals $row['petals'] = $entity->petals;   // Season $row['season'] = $entity->season;   return $row + parent::buildRow($entity); }   /** * {@inheritdoc} */ public function render() {   $build = parent::render();   $build['#empty'] = $this->t('There are no flowers available.'); return $build; }   }

In this class that extends the ConfigEntityListBuilder, we implement three methods. The buildHeader() method is responsible for creating the table header of our overview page whereas buildRow() will create the rows based on the number of entities and their values. Lastly, we are overriding the render() method so that we can specify a custom message to display in case there are no entities to show (personal preference). And that's basically it with the list builder class.


There are a few more things we need to take care of in order to round up our configuration entity type. The first one has just became kind of mandatory so I'll start with that: the configuration schema. So let's quickly create the folder structure inside our module (config/schema/) and inside a file called flower.schema.yml we can have the following:

# Schema for the configuration files of the Flower module. flower.flower.*: type: mapping label: 'Flower' mapping: id: type: string label: 'Flower identifier' uuid: type: string label: 'UUID' name: type: label label: 'Name' color: type: string label: 'Color' translatable: true petals: type: integer label: 'Number of petals' season: type: string label: 'Season' translatable: true

On the first line (after the comment) we start defining the schema for the (flower module).(flower configuration entity type).(all flower configuration entities). And it follows to map all the entity properties and specify what data type they are. Although the uuid property was not defined by us, Drupal adds it by default and we can specify it here.

As far as I could tell, the label-typed properties become translatable automatically whereas for all the rest we want translatable we can specify translatable: true. Translation is one of the biggest reasons for which we use these schemas for configuration entities.

And now that the schema is taken care of, it's time for some finishing touches. First, let's create our routes so that we can access everything in the browser. Inside of a file called flower.routing.yml in the module root folder, add the following:

flower.list: path: '/admin/structure/flowers' defaults: _entity_list: 'flower' _title: 'Flowers' requirements: _permission: 'administer site configuration' flower.add: path: '/admin/structure/flowers/add' defaults: _entity_form: 'flower.add' _title: 'Add a new flower' requirements: _permission: 'administer site configuration' flower.edit: path: '/admin/structure/flowers/edit/{flower}' defaults: _entity_form: 'flower.edit' _title: 'Edit flower' requirements: _permission: 'administer site configuration' flower.delete: path: '/admin/structure/flowers/delete/{flower}' defaults: _entity_form: 'flower.delete' _title: 'Delete flower' requirements: _permission: 'administer site configuration'

For more information about the structure of a route file (and what the above keys actually mean), please consult this documentation page. But an important take-away are the paths we defined at admin/structure/flowers.

Second, on the flower overview page, we'd probably like a link to add new flowers to the site. So let's create another YML file in the root of our module called flower.local_actions.yml to define that link:

flower.add: route_name: 'flower.add' title: 'Add flower' appears_on: - flower.list

This is a simple local action link definition called flower.add that uses the flower.add route and appears on the page given by the route flower.list. For more information about defining local actions, consult this documentation page.

Third, we can create a menu link under the Structure admin menu that will take us to the flower overview page. So inside of a file called flower.menu_links.yml in the module root folder, add the following:

flower.list: title: Flowers description: 'Administer the flower entities' parent: system.admin_structure route_name: flower.list

Here we create a link called flower.list found under the system.admin_structure link and that uses the flower.list route name. Simple.

Finally, we need to create the auto loader function that will be used by the machine_name form element to check whether an entity with a given machine name already exists (on the flower add form). So inside the flower.module file, create this function:

/** * Menu argument loader. Returns a flower entity * * @param $id * @return \Drupal\Core\Entity\EntityInterface|static */ function flower_load($id) { return FlowerEntity::load($id); }

And don't forget to use the FlowerEntity class at the top of the file:

use \Drupal\flower\Entity\FlowerEntity;

And that should be about it. Clear the caches, make sure the module is enabled, and start poking at it. Navigate to /admin/structure/flowers and create, edit, delete flower entities. Additionally, you can turn on configuration translation and translate all your entities into multiple languages. Cool, no?


In this tutorial we've looked at how we can create our own simple configuration entity type in Drupal 8. The alpha13 version (latest at the time of writing) has been used for this, so make sure that if you are using a newer one you make the necessary code adaptations if needed.

In Drupal 7 we do not have configuration entities and we are left with creating custom tables that hold data meant as configuration. And obviously, integration with the modest D7 entity API is practically inexistent. This all changes in Drupal 8 with the development of a robust entity API - fully integrated with the multilingual and configuration systems. Because of this, we now have exportable and translatable configuration entities used to manage more complex data that is not content.

And with all these new developments, we are being introduced to a few new concepts that can scare us a bit (services, dependency injection, plugins, OOP and so on). However, once we get used to them a bit, they will become a friend rather than foe and open the door to more sane, performant and modern development within the Drupal framework.

Miles Carter: Drupal views templating tutorial: Outputting the respective image fields of multiple associated taxonomy term references

Planet Drupal - Mon, 14/07/2014 - 01:50

Courtesy of - Miles J Carter Photos on the Web Blog
Source URL : Drupal views templating tutorial: Outputting the respective image fields of multiple associated taxonomy term references

Using a custom field template to output taxonomy term references as their respective image fields, rather than as text or a link

The ingredient icons are term reference fields formatted to output as their respective image fields, rather than as a link or text

The example situation is where a view displays a list of nodes or fieldable entities, for our example items on a menu, and each of these has one or more taxonomy term references, in this example the main ingredients. While it’s simple to output the term references as plain text or a link, showing an image or other field attached to the term reference instead of this presents problems.

Using views relationships

The obvious solution is to create a relationship to the taxonomy in the view set up, and add the image field via the relationship. However, this currently presents issues with duplicate rows being output. If an item in the view has more than one term reference, it is displayed once for each term reference. Because of how views works, setting “distinct” and “pure distinct” in the query settings does nothing as they are technically distinct results (each has a different term reference).

The views_distinct module should offer a solution to this kind of problem, but currently it does not work in a way that can aggregate the required fields while filtering duplicates in this situation.

Creating the custom field template

In our example view, no relationship is used and the relevant term reference field is included in the field list

If you have never made a views template before, click the link “Information” in the Other section of the view:


This displays a list of possible templates to use in customising your view for each field in the view. The template names shown are ordered from least specific to most specific – the filename of the template determines which situtations it is used. The bolded template is the one currently being used. To make a new custom template, create a file in the theme’s templates directory with the name. Click the link next to it to get the default code which should go into the template. In this case we wish to control output in all situations the field appears, so the first custom template option (highlighted) is that used.


From the helpful comment at the top of the file, it can be seen that the contents of the view item can be found in the $row object. By debugging this object the location of the ingredients term references and their respective image fields can be found.

In this case the term reference field data is at:


and the image field at:


Where INDEX is the array index for multiple items.

The field_view_field() function is useful here to display the image field without needing to worry about URLs and allows control of formatting, e.g. image style presets. We also need to use an isset() condition to prevent warnings being thrown where rows don’t have any term references.

Putting this all together gives the example code:

if(isset($row->field_field_ingredients)) {
        $term = $row->field_field_ingredients;

        foreach($term as $ingredient){
                print render(field_view_field('taxonomy_term', $ingredient['raw']['taxonomy_term'], 'field_image',));

This outputs the image, but at it’s original size and with an ugly label that says “Image:”. To fix this, we need to use the optional fourth parameter of the field_view_field() function to control display and formatting of the field. The line inside the foreach() loop becomes:

print render(field_view_field('taxonomy_term', $ingredient['raw']['taxonomy_term'], 'field_image',
array('label'=>'hidden', 'settings' => array('image_style' => 'thumbnail'))));

This hides the label and sets the image style preset for the output to ‘thumbnail’.

Final code:

if(isset($row->field_field_ingredients)) {
        $term = $row->field_field_ingredients;

        foreach($term as $ingredient){
                print render(field_view_field('taxonomy_term', $ingredient['raw']['taxonomy_term'], 'field_image',
                array('label'=>'hidden', 'settings' => array('image_style' => 'thumbnail'))));

PreviousNext: Writing a custom Drupal Search API processor

Planet Drupal - Mon, 14/07/2014 - 01:07

When working with the Search API Drupal module, sometimes we need to programmatically add information that is not available for indexing as a field. Lucky we can write our own custom pre-processor to provide this information to the index.

The master key is 4096 bit, stored in a safe place, and 2 subkeys 3072 bit, stored in an FSFE Smartcard (I cannot store 4096 keys there).

I have carefully used the FSFE SmartCard Howto and “Creating the perfect GPG keypair” by Alex Cabal for strenghtening hash preferences and creating revocation certificate.

It seems everything works as intended. Passphrase is strong and this time I will not forget it.

As first celebration, 1/2 lt icecream is waiting for me after dinner :)

People knowing me and around Madrid, please send me an encrypted mail as test or normal communication, and ping me to meet and sign keys :)

One more step towards involvement in Debian and free software, controlling my digital life and communications, and becoming familiar with these technologies so I can teach them to my son as ‘the natural way’.

Steve Kemp: A brief twitter experiment

Planet Debian - Sun, 13/07/2014 - 21:08

So I've recently posted a few links on Twitter, and I see followers clicking them. But also I see random hits.

Tonight I posted a link to http://transient.email/, a domain I use for "anonymous" emailing, specifically to see which bots hit the URL.

Within two minutes I had 15 visitors the first few of which were:

IP User-Agent Request;GET /robots.txt;GET /robots.txt CPython/2.7.2+ Linux/3.0.0-16-virtualHEAD / ();GET / (gzip)HEAD / (gzip)HEAD /;GET /robots.txt (compatible; TweetmemeBot/3.0; +http://tweetmeme.com/)GET / API/2.0 +metauri.comGET / (compatible; Yahoo! Slurp; http://help.yahoo.com/help/us/ysearch/slurp);GET /robots.txt

So what jumps out? The twitterbot makes several requests for /robots.txt, but never actually fetches the page itself which is interesting because there is indeed a prohibition in the supplied /robots.txt file.

A surprise was that both Google and Yahoo seem to follow Twitter links in almost real-time. Though the Yahoo site parsed and honoured /robots.txt the Google spider seemed to only make HEAD requests - and never actually look for the content or the robots file.

In addition to this a bunch of hosts from the Amazon EC2 space made requests, which was perhaps not a surprise. Some automated processing, and classification, no doubt.

Anyway beer. It's been a rough weekend.

Freelock : I've got a theory: The Scientific Method applied to web site performance

Planet Drupal - Sun, 13/07/2014 - 18:10

What can you do about this page being so slow? That's a question we've been asked by half a dozen customers in the past 6 months, and as it turns out, we can do quite a lot.

One of my long-standing complaints about Drupal is that it's a resource hog. That's an issue we can generally help by throwing lots of hardware and caching systems at the problem -- but that's not the kind of performance issue these clients were having.

Russ Allbery: Review: Neptune's Brood

Planet Debian - Sun, 13/07/2014 - 06:54

Review: Neptune's Brood, by Charles Stross

Series: Freyaverse #2 Publisher: Ace Copyright: July 2013 ISBN: 1-101-62453-1 Format: Kindle Pages: 325

Neptune's Brood is set in the same universe as Saturn's Children, but I wouldn't call it a sequel. It takes place considerably later, after substantial expansion of the robot civilization to the stars, and features entirely different characters (or, if there was overlap, I didn't notice). It also represents a significant shift in tone: while Saturn's Children is clearly a Heinlein pastiche and parody, Neptune's Brood takes its space opera more seriously. There is some situational humor — assault auditors, for example — but this book is played mostly straight, and I detected little or no Heinlein. This is Stross fleshing out his own space opera concept.

This being Stross, that concept is not exactly conventional. This is a space opera about economics. Specifically, it's a space opera about interstellar economics, a debt pyramid, and a very interesting remapping of the continual growth requirements of capitalism to the outward expansion of colonization. The first-person protagonist comes from a "family" (as in Saturn's Children, the concept exists but involves rather more aggressive control of the instantiated "children") of bankers, but she is a forensic accountant and historian who specializes in analysis of financial scams. As you might expect, this is a significant clue about the plot.

Neptune's Brood opens with Krina in search of her sister. She is supposed to be an itinerant scholar, moving throughout colonized space to spend some time with various scattered sisters, spreading knowledge and expanding her own. But it's clear from the start of the book that something else is going on, even before an assassin with Krina's face appears on her trail. Unfortunately, it takes roughly a third of the book to learn just what is happening beneath the surface, and most of that time is spent in a pointless interlude on a flying cathedral run by religious fanatics.

The religion is a callback to Saturn's Children: robots who are trying to spread original humanity (the Fragiles) to the stars. This mostly doesn't go well, and is going particularly poorly for the ship that Krina works for passage on. But this is a brief gag that I thought went on much too long. The plot happens to Krina for this first section of the book rather than the other way around, little of lasting significance other than some character introductions occurs, and the Church itself, while playing a minor role in the later plot, is not worth the amount of attention that it gets. The best parts of the early book are the interludes in which Krina explains major world concepts to the reader. These are absolutely blatant infodumping, and I'm not sure how Stross gets away with them, but somehow he does, at least for me. They remind me of some of his blog posts, except tighter and fit into an interesting larger structure.

Thankfully, once Krina finally arrives on Shin-Tethys, the plot improves considerably. There was a specific moment for me when the book became interesting: when Krina finds her sib's quarters in Shin-Tethys and analyzes what she finds there. It's the first significant thing in the book that she does rather than have done to her or thrust upon her, and she's a much better character when she's making decisions. This is also about the point where Stross starts fully explaining slow money, which is key to both the economics and the plot, and the plot starts to unwind its various mysteries and identify the motives of the players.

Even then, Krina suffers from a lack of agency. Only at rare intervals does she get a chance to affect the story. Most of what she did of relevance to this book she did in the past, and while those descriptions of the backstory are interesting, they don't entirely make up for a passive protagonist. Thankfully, the other characters are varied and interesting enough, and the political machinations and cascading revelations captivating enough, that the last part of the book was very satisfying even with Krina on for the ride.

This is a Stross novel, so it's full of two-dollar technical words mixed with technobabble. However, it shares with Saturn's Children the recasting of robots as the norm and fleshy humans as the exception, which means much of the technobabble is a straight substitution for our normal babble about meaty bodies and often works as an alienation technique. That makes it a bit more tolerable for me, although I still wished Stross would turn down the manic vocabulary in places. This bothers some people more than others; if you had no trouble with Accelerando, Neptune's Brood will pose no problems.

I don't think the first section of this book was successful, but I liked the rest well enough to recommend it. If you like your space opera with a heavy dose of economics, a realistic attitude towards what deep space exploration without faster-than-light technology, and a realistic perspective on the hostility of alien planets to Earth life, Neptune's Brood is a good choice. And any book that quotes David Graeber's Debt, and whose author has clearly paid attention to its contents, wins bonus points from me.

Rating: 8 out of 10

Dirk Eddelbuettel: RcppArmadillo 0.4.320.0

Planet Debian - Sun, 13/07/2014 - 01:43
While I was out at the (immensely impressive and equally enjoyable) useR! 2014 conference at UCLA, Conrad provided a bug-fix release 4.320 of Armadillo, the nifty templated C++ library for linear algebra. I quickly rolled that into RcppArmadillo release 0.4.320.0 which has been on CRAN and in Debian for a good week now.

This release fixes some minor things with sparse and dense Eigen solvers as shown in the NEWS entry below.

Changes in RcppArmadillo version 0.4.320.0 (2014-07-03)
  • Upgraded to Armadillo release Version 4.320 (Daintree Tea Raider)

    • expanded eigs_sym() and eigs_gen() to use an optional tolerance parameter

    • expanded eig_sym() to automatically fall back to standard decomposition method if divide-and-conquer fails

    • automatic installer enables use of C++11 random number generator when using gcc 4.8.3+ in C++11 mode

Courtesy of CRANberries, there is also a diffstat report for the most recent release. As always, more detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.

This post by Dirk Eddelbuettel originated on his Thinking inside the box blog. Please report excessive re-aggregation in third-party for-profit settings.
